All Door Entry Lock/Unlock Functions and Wireless Functions do not Operate: Description
WARNING: This page is about a different car, the 2011 Lexus RX 350. However, it is still accessible from the selected car via links, so may be relevant.
When the entry door lock and unlock functions and wireless door lock and unlock functions do not operate, radio wave interference, or a malfunction in the key or signal circuit between the door control receiver assembly and certification ECU (smart key ECU assembly) is suspected. The signal circuit is shared by the entry function and wireless door lock function.
